Q

Cancer that invades the bone marrow causes what?

A

anemia, thrombocytopenia, and reduce production of healthy WBC’s

22
Q

Cancer that spreads to the liver causes what?

A

malnutrition and death

23
Q

Radiation tx

A

destroys cancer cells with minimal exposure to normal cells

local treatment

24
Q

Radiation dose

A

amount of radiation absorbed by the tissue

always less than exposure

25
Q

Teletherapy

A

radiation source is external to the PT

PT is not radioactive

26
Q

Brachytherapy

A

radiation in direct, continuous contact with the tumor

the patient emits radiation and is hazardous to others for 48 hours after

27
Q

Chemotherapy

A

major tx

has some selectivity for killing CA cells over normal cells

28
Q

Types of normal cells effected by chemotherapy

A

those that divide rapidly such as skin, hair, intestinal tissues, spermatocytes, and blood forming cells

29
Q

Nadir

A

the time when bone marrow activity and WBC counts are at their lowest level after chemo

30
Q

Frequency of chemotherapy administration

A

every 3-4 weeks

on average 4-12 times

31
Q

Extravasation

A

the major complication of IV infusion
drug leaks into the surrounding tissues
can cause severe tissue damage
Surgery may be needed

32
Q

Side effects of chemo

A 
anemia
thrombocytopenia
neutropenia 
mucositis
changes in cognitive function
N/V
peripheral neuropathy
33
Q

Neutropenia

A

greatly increases risk for infection and can cause death

34
Q

Neutropenia tx

A

BMR’s (biologic response modifier) to stimulate bone marrow production

35
Q

BMR’s ex

A

neupogen, procrit/epogen, neumega

36
Q

Thrombocytopenia

A

increases risk for bleeding

<20K platelets may have spontaneous bleeding and need a transfusion

37
Q

Mucositis

A

open sores on mucous membrane
especially stomatitis
PT should drink 3L of H2O daily

38
Q

Hormonal manipulation

A

aimed at decreasing hormones to slow CA growth

39
Q

Tamoxifen

A

estrogen antagonist-agonist
used to tx breast CA
binds to estrogen so it is unavailable for cells

40
Q

Tamoxifen se

A 
hot flashes and wt gain
increased hair growth
decreased breast tissue or gynnecomastia in men
sexual disfunction
increased risk of DVT
41
Q

Photodynamic therapy

A

Selective destruction of cancer cells through a chemical reaction triggered by different types of laser light
Dye is administered IV and collects in CA cells in 2-3 days

42
Q

Photodynamic therapy se

A

photosensitive for 12 weeks (sunblock will not prevent sunburn)
eye/skin pain

43
Q

Oncologic Emergencies

A 
sepsis
disseminated intravascular coagulation (DIC)
SIADH
spinal cord compression
hypercalcemia
superior vena cava syndrome
44
Q

disseminated intravascular coagulation (DIC)

A

often caused by sepsis
seen in leukemia
clotting followed by bleeding

45
Q

disseminated intravascular coagulation (DIC) sx

A

pain, strokelike symptoms, dyspnea, tachycardia, oilguria, and tissue death

46
Q

SIADH sx and tx

A

hyponatremia, weakness, muscle cramps, fatigue, loss of appetite, seizures, coma
tx: Fluid restrictions

47
Q

Hypercalcemia

A

usually seen in bone CA

48
Q

Hypercalcemia sx and tx

A

Fatigue, N/V, constipation, polyuria, etc

tx: Increase hydration, calcitonin

49
Q

Superior vena cava syndrome

A

Occurs from compression of the SVC

50
Q

Superior vena cava syndrome sx

A

edema of the face especially around the eyes upon awakening, tightness of the shirt collar, edema in the arms and hands, dyspnea, erythema of the upper body, nose bleeds, ALOC
